The part first reaches the top of the preliminary shaping groove 14. The upper mold forming plate 4 moves down, causing the preliminary riveting block 22 to be embedded into the preliminary shaping groove 14, and the part is initially shaped. After shaping, the part continues to move with the part conveying wheel 24. When it reaches the side of the cylinder 6, the pneumatic press 7 delivers air pressure to the cylinder 6 through the air pipe 8, driving the mating extrusion rod 16 to extend and penetrate the preliminarily shaped part. Subsequently, the upper mold forming plate 4 continues to move downward, driving the mating riveting block 23 closer to the multi-directional riveting groove 15.

After the riveting is completed, the cylinder 6, under the action of the second return spring 20, drives the mating extrusion rod 16 to return to its original position, the upper mold forming plate 4 moves upward, and the rotary motor 13 drives the part conveying wheel 24 to send the finished part to the finished product carrier frame 12. The rotary motor 13 then adapts to its position through the third return spring 27, and the equipment returns to its initial state, ready for the next round of riveting operations.
